We were
discussing Boyle’s
law and Charles
law in our recent post, we have also seen Avogadro’s law in our previous post
and today we are going to understand here P-V-T surface in thermodynamics.
We will see another important topic i.e. Stirling cycle and Ericsson cycle in the category of thermal engineering in our next posts.
As we know very well that equation of state for an ideal gas deals with the relationship between
pressure, volume and temperature. If we will plot above mentioned variables
along x, y and z axis then we will have one surface which will indicate the equation
of state i.e. PV=RT
And this
surface will be termed as P-V-T surface in thermodynamics. Following figure
displayed here indicates the P-V-T surface for an ideal gas.
Over this P-V-T
surface, each point will indicate equilibrium state and each line will indicate
the process.
P-V-T surface indicate lots of information at one glance, but practically in thermal engineering
it will be quite easy to work with two dimensional diagram such as P-T, V-T and
P-V diagrams.
